Anyone on here have an IMS failure with Tiptronic trans?

Yes, cruising on a highway. But what about just driving round town, which most Boxsters do A LOT of? You'll be constantly tripping the Variocam.

The fact is, most Boxsters will have done a lot of driving around town. And the IMS doesn't fail in most Boxsters.

Anyway, you'll be relieved to hear I always drive mine like I stole it once it's nicely warmed up!

At least here in the US, nobody revs the engine past 2500 rpm making an upshift in town (no joke) Remember, "mericans" << say that with the redneck accent, are used to TORQUE. They are semi preprogrammed to shift early (I see this all the time)

Take a new person out on test drive? They will short shift the car!!

I have spent quite a bit of time running around the UK for weeks on end, I *know* how they drive, and I know what they are used to driving: vehicles with little torque/high revving engines or diesel's with gobs of torque and short shifting.

I ran around the Elstree area frequently in Turbo Mitsubishi's, and downtown London.

Even if you're right about US owners barely breaching 2k rpm (and gotta be honest, don't really buy it!), here in the UK it's a dead cert most Boxsters will have spent tons of time passing through that rev range.

If you're right, there'd be an epidemic of IMS failures in the UK. But I've been using Boxanet forum in the UK for three years, loads of users, just a couple have had IMS failure in that time. Still can't see this is what causes the failures.

How about this: it greatly contributes to failures in my area (Los Angeles)

Like I said Brad, I'm not arguing with the engineering side of it. But there are a few realities here that can't be argued with and they have nothing to do with the number of Boxsters I own or have been in contact with. My views have nothing to do with my car.

1. The majority of UK Boxsters will have spent lots of time in traffic routinely tripping that rev range
2. The majority of UK Boxsters haven't suffered IMS failure
3. There's no reason California Boxsters should be any different

Seriously, if you were right about this being a significant contributor to IMS failure it would be total carnage over here in the UK and across Europe for that matter!
